    13 years later I am watching this video and it's still extremely clear and useful. Thank you!
    This video has already raised several generations of students :)

    You were born to teach. You just explain everything as if you were explaining it to children, you make it easy to understand, thanks so much!

    I must confess that I know some statistics; I graduated from college with a honors degree in statistics. These videos are helping me deepen my knowledge of statistics--40 years after graduation. Thanks, Sal!

    p x=3 shouldnt it be 0.7 cubed times 0.3 cubed (not squared)?
    apart from that great video cheers

    hi Sal! great as always!
    shouldn't it be: P (X=3) = 0.7^3*0.3^3 rather than 0.7^3*0.3^2?

  • @Fareeed92
    @Fareeed92 9 ปีที่แล้ว +3

    Why doesn't he just use the binomial probability formula.
    Eg.
    p(x=2)
    6C2(0.7)^2 x (1-0.7)^(6-2)
    Its a little confusing when he mix permutation with this. What is the difference between the two?

    @1234LMAO12345 I did that A level short course thing when i was in year 11(got my a* in gcse etc),take my word, don't let it stress you out and interfere with any of your other GCSEs. I'm now in college doing further maths and the stuff you will be doing now in school (such as binomial distribution) is taught much better and is very easy when you're in college. They really shouldn't do the A level thing they put you through while you're still in school cos it just stresses you out like it did me

    for the equation at the probability of making 3 shots in p(x=3) at 10:37, shouldnt that be 0.3^3 since u are making 3 shots? not 0.3^2?
    I may be missing something, but am i right or wrong? =S

  • @bubblewrap55
    @bubblewrap55 8 ปีที่แล้ว

    Hey Guys, help me out here! If you ask me the probability of making one shot, for me I would say p=30%.
    While saying this, I am actually providing an estimate that I'll be able to make 3 out of 10 shots for sure (means, P(X=3) given n=10 is 100%)
    But then using same numbers n=10 and p=3 I calculate the binomial probability of making 3 shots out of 10 and it is 26.68%!

    • @superjj1850
